Qualcomm Platform Update:

How to connect: in the powered on state with adb debugging enabled. Full manual is located in the help section of Sigma website.

Benefits:

No more need to ask Huawei support to give you bootloader password for these new models. Since this update you can get/unlock it instantly and go on to SP-unlock.

Reset bootloader password: unlike restoring phone's bootloader lock by flashing or using 3rd party tools, with Sigma bootloader will be restored to its initial factory state without any traces left in the firmware.
